I am trying to create a manager for my autostarts. It should read an XML file and then start my programs with a custom delay. For example:
<startup id="0">
<name>Realtek Audio Manager</name>
<process arguments="-s">C:\Program Files\Realtek\Audio\HDA\RtkNGUI64.exe</process>
<delay>5</delay>
</startup>
This runs the specified process (C:\Program Files\...\RtkNGUI64.exe -s
) after 5 seconds.
Now, three of the programs won't start, giving me a System.ComponentModel.Win32Exception
: "Das System kann die angegebene Datei nicht finden." ("The system was not able to find the specified file.")
But the XML is parsed correctly, and the file I want to start is at the location I specified in the XML file.
The problem concerns only these three files:
Intel HotkeysCmd - C:\Windows\System32\hkcmd.exe
Intel GFX Tray - C:\Windows\System32\igfxtray.exe
Intel Persistance - C:\Windows\System32\igfxpers.exe
I think that the problem comes from the location of the files: they all are located in C:\Windows\System32, and all the other, working programs are located outside (C:\Program Files, C:\Program Files (x86), D:\Program Files, %AppData%
)
Do I have to give my program some kind of access rights to start programs in C:\Windows\System32? How would I do that?
If not, what could be the reason I get errors with these programs?
EDIT - my code:
delegate(object o)
{
var s = (Startup) o;
var p = new System.Diagnostics.Process
{
StartInfo =
new System.Diagnostics.ProcessStartInfo(s.Process, s.Arguments)
};
try
{
s.Process = @"C:\Windows\System32\igfxtray.exe"; // For debugging purposes
System.Diagnostics.Process.Start(s.Process);
icon.ShowBalloonTip(2000, "StartupManager",
"\"" + s.Name + "\" has been started.",
System.Windows.Forms.ToolTipIcon.Info);
}
catch (System.ComponentModel.Win32Exception)
{
icon.ShowBalloonTip(2000, "StartupManager",
"\"" + s.Name + "\" could not be found.",
System.Windows.Forms.ToolTipIcon.Error);
}
}
Clearly you are using a 64-bit version of Windows. The c:\windows\system32 and c:\program files directories are subject to a feature called "file system redirection". It is an appcompat feature, it helps to ensure that 32-bit processes don't try to use 64-bit executables. They'll get redirected to c:\windows\syswow64 and c:\program files (x86).
So when you try to start a file in c:\program files\realtek\etcetera, your 32-bit program will be redirected to c:\program files (x86)\realtek\etcetera. A directory that doesn't exist, kaboom. Same ingredient for igfxtray.exe
You'll need to change your program's platform target so it can run as a native 64-bit process and avoid the redirection problem you now have. Project + Properties, Build tab, change the "Platform target" setting to AnyCPU.
